How do I install an SE with a large SCSI RAID array?
There have been problems with LCFG installation on client machines using SCSI and/or RAID arrays due to the kernel not having the correct drivers.The important thing here is that you require the kernel driver for your scsi disk to be loaded before the disk is partitioned and the kernel driver must be loaded at all future reboots.
On the node where you have the need for SCSI set
#define SCSI_HOSTADAPTER aic7xxx
#define SCSI_MODPROBE aic7xxx
before the redhat-73-cfg.h file is included in the profile.
Obviously replace for correct driver if you are using an
Adaptec SCSI controller.
Setting this does a number of things, during installation:
- /sbin/modprobe SCSI_MODPROBE is issued to load the driver before partiontions are created.
- The default disk to partition on is changed to sda instead of hda, this includes where GRUB should be installed. This may in fact not be what you want if you have an existing ide disk for the system and in which case write your partition table from scratch is possibly the best idea.
- The file /etc/modules.conf is filled in with the correct driver so that the driver is loaded correctly at boot time.
- Finally mkinitrd is called to create an initial root disk to be used during future reboots.
